Hello,Thanks for the question. The surgeon will look at the hips aligned making sure any hardware (pins, plates, rods, or replacement parts) are in good alignment and "well seated" - meaning that a new hip's components are not coming loose. He will also look for calcification along fracture lines.3 months is sufficient time for healing. It is not uncommon for the hip to hurt after it was fixed. If the surgery went well and the bone healed well, be reassured that the joint is good and safe to use it. The pain is probably from surrounding muscles, tendons, and ligament inflamation or soreness. Also, check leg lengths. Often after hip surgery, the operative leg length changes and can have an effect on pain levels and function.Also, remember that she should continue to do her prescribed exercises.The orthopedist can re check the hip at any time to make sure everything is intact and stable. You may consider asking her physician about pain medicine too.

All the best to you and your Mom. Let us know if you have any more questions. Take care.
